You can see the full implementation of the device and configuration descriptors of the UHK in LUFA here. The GenericHID interface serves as a communication channel, to exchange configuration information for all the special features of the keyboard. However, as a custom programming keyboard, the UHK also exposes a mouse interface descriptor, because the user can program arbitrary keys of the keyboard to control the mouse pointer so the keyboard can be used as a mouse. Most standard keyboards only expose a single keyboard interface descriptor, which makes sense. Let’s see the descriptors structure of the UHK: To make matters even more complex, a device can implement not only one but multiple functions. These descriptors tell the host computer the type and properties of the device being connected, and are represented by a tree structure. When plugging a device into the USB port, the device has to transfer some special data structures called USB descriptors. It enables these processors to become the brains of printers, MIDI devices, keyboards, or almost any other type of USB device. When it comes to USB-capable AVR microcontrollers, the Lightweight USB Framework for AVRs ( LUFA) is the library of choice. The Arduino Micro development board is an ideal candidate for this purpose, because it features the ATmega32U4 microcontroller - an AVR microcrontroller and the same processor that is the brains of the UHK. Therefore, let our keyboard tutorial journey begin! Step One: A Keyboard Without Keysįirst up, let’s make a USB keyboard that emits the x character on a once-per-second basis. What if we start with something simple, like an Arduino board, and gradually build it up to be the Ultimate Hacking Keyboard? It should not only be more digestible but extremely educational. How do you make a keyboard?Īfter dedicating thousands of hours of my life to this topic, it’s a hefty challenge for me to give a short answer, but there’s an interesting way to answer to this question.
A basic understanding of electronic circuit diagrams may help you follow along. In this article, I’ll describe the design of how this electronic masterpiece works.

Going from a software background, knowing nothing about electronics, to designing and building a powerful, marketable hardware device, is an interesting and fascinating experience. We’re making daily progress, and the launch of our crowdfunding campaign is within reach. Nowadays, the Ultimate Hacking Keyboard is a reality. I managed to learn a whole new skill set, persuade a friend of mine, András Völgyi, mechanical engineer extraordinaire, to join to the project, gather some key people, and devote enough time to creating working prototypes. Soon I started dedicating my free time to working on the project. This realization was followed by an overwhelming feeling of excitement as I thought about customizing the best keyboard for developers - and later, the realization that, as a freelance embedded software developer, I was hopelessly clueless about hardware.Īt the time, I was quite busy with other projects, but not a day passed when I didn’t think about building the hacker keyboard. I had to move my hands between the various blocks of my keyboard excessively, hundreds if not thousands of times per day, and my hands were uncomfortably close to each other.

Working one day in August of 2007, I couldn’t help but realize that my regular PC keyboard didn’t serve me as much as possible.
